JOHN WALSH, OF GALENA, ILLINOIS.

IMPROVEMENT IN MlLLSTOvNE-BALANCE'S.

Specification forming part of Letters Patent No. 150,639, dated May 5, 1874 application iled April 20, 1874.

To all whom t may concern:

Beit known that I, JOHN VVALS'H, of Galena, in the county of J o Daviess and State of Illinois, have invented certain Improvements in Millstone-Balance, of which the following is a specication, reference being had to the accolnpanyin g drawin gs.

My invent-ion consists in the construction of a lnillstone-balance, as will be hereinafter vm ore fully Set forth. u

lThe figure in the drawings more fully represents my invention.

A represents an ordinaryimillstone, provided with one or more of the usual hoops, J. A narrow groove is left around the circumference ofthe stone, both at top and bottom, between the stone and the hoops, as shown. E repre sents vertical rods or bolts, which are connected to'bent lugs or ears F, that catch into the groove, hereinbefore described. D represents one or morehorzontal bars, which are.

perforated near each end, and through which the rods or .bolts E are passed, so that` the bars are secured on the rods or bolts on the exterior of the stone, and a short distance away from it.

The bar (or bars) can' be moved up and down on the rods, and are provided with jamnnts E', by which they may be fastened at any point thereon. The body of the bar is recessed or chambered nearly or entirely its entire length, as shown, so that instead of using the sliding weights C upon it, it may berendered heavier at any point desired by casting lead into it at such point.

vthe bars on the stone.

The bar or bars D may be either made to entirely or partially encircle the millstone, and when made entirely around the stone, the jam-nuts F. should be arranged on the outer face of the bars opposite to the rods E, instead of on the end of the bars, as now shown. rI he rods E, bars D, and bent lugs may be moved around the stone from one point to another by loosening the nuts on the ends of the bolts E, and sliding the lugs around the groove between the hoops and the stone.

Whenever the vmillstone runs unevenly, or higher on one side than on the other, it may be readily brought to a level by adjusting the bars or weights on the exterior of the stone.

What I claim is- In a inillstone-balance, the horizontally and vertically adjustable and chamber-ed or re cessed bar D, supported parallel and near to the periphery of the stone, as shown, in combination with the rods E, set-screws E', and adjusting-lugs F, as and for the purposes set forth.
